Aerojet Rocketdyne has provided a payload of six lithium-ion batteries to the International Space Station in an effort to keep the power supply needed to help astronauts continue their research aboard the station.
The lithium-ion batteries incorporate safety features such as voltage, temperature and cell-overcharge monitoring and will replace 12 nickel hydrogen batteries at ISS, Aerojet Rocketdyne said Tuesday.
Eileen Drake, Aerojet Rocketdyne CEO and president, said electrical power systems play a critical role for astronauts who live on the ISS and for their research activities.
The batteries are built to last up to 10 years and Aerojet Rocketdyne will supply an additional 18 lithium-ion batteries to the ISS in 2018, 2019 and 2020.
Aerojet Rocketdyne has produced 31 lithium-ion Orbital Replacement Units to date, including two engineering units, two qualification units and 27 flight units of the power system.
